high performances microphone system
Brief description
The MCR42 is a high performance microphone re-
ceiver suitable for broadcast and high profes-
sional applications.
Thanks to Wisycom movable lter technology,
MCR42 is able to work in a bandwidth up to 240
MHz, still keeping an exceptional selectivity and in-
termodulation immunity.
This miniature design allows to integrate a DUAL
TRUE DIVERSITY receiver while keeping a small
size to t camera slot in:
- Ikegami/Panasonic (UNISLOT™);
- Philips/Thomson/Grass Valley;
- Sony.
The audio receiver block is fully digital to allow a
better quality, digital output and emulation of most
of companding chipsets. It supports also AES3 au-
dio output with an overall sounds delay below 1.5
msec.
MCR42 is designed to be:
•“easy & quick to use” thanks to automatic setup
functions (i.e. frequencies, squelch, scan), remote
conguration utilities (thru infrared), an OLED dis-
play with intuitive context menu navigation.
•“extremely exible”, with an incredible frequen-
cy agility up to 240 MHz. Moreover the DSP board
allows analogue and digital (AES3) output, with
multi-companding compatibilities and other digital
features.
•“best in class performances”, thanks to the lat-
est Wisycom technology the unit has extreme RF
sensitivity and immunity and superb audio quality.
•“a durable & upgradable investment”, thanks
to the very robust design (aluminum housing) and
the possibility to upgrade/enhance units perfor-
mances.
Moreover MCR42 system is already set up for the
exclusive PTT function (remote command), devel-
oped and patented by Wisycom and now appreciated
in the broadcast world:
Simply pushing this button (PTT), the pre-
senter causes the remote switching of the
receiver’s output-line, from the “main line” to
the additional “intercom line”, in order to be
able to talk “off-air” directly with the technical
team. Then all PTT’s MICs can be connected
in pre-fading allowing a clever intercom
setup.

MCR42: main block diagram
One of the milestones in the design of the MCR42 is
high reliability: most of the circuitry of the receiver
is independent one from each other.
Above a schematic with an overview of main receiv-
er functions.
For each antenna the RF signal is split in the receiver
1 and in the receiver 2 (antenna A and antenna B)
with a wide band splitter. In this way any one receiv-
er could be tuned in any frequency of the switching
range (typ. 240 MHz).
Receiver 1 and 2 are diversity receivers: each one is
made of two receivers tuned on the same frequency,
hereafter called section A and section B. The re-
ceiver 1 section A and the receiver 2 section A are
connected to the antenna A, the receiver 1 section
B and the receiver 2 section B are connected at the
antenna B.
Each receiver has its own demodulated signal and
its own RSSI signal (Receiver Signal Strength Indi-
cation); a DSP selects or combines signals from
section A & B to have the best audio.
The demodulated signal ows to the digital audio
processor.
Data signalling detection and demodulation:
the data sub carrier is digitally ltered to a very se-
lective equivalent bandwidth (3Hz). Each lter has
its own data demodulator, one for medium speed
data detection at the output of the rst lter and one
at low speed data detection at the output of the sec-
ond lter. All the two demodulators are connected to
the supervisor micro controller for the data battery
detection and signalling.
Digital audio processor: the demodulated signal
is ltered by an anti aliasing low pass lter and then
converted in the digital domain with a 96KHz 24bit
audio A/D converter. The digital signal processor
(DSP), working in double precision, replicates all the
analog functions with very high accuracy, ultra low
distortion and without typical analog problems like
components tolerances or long term drifts or tem-
perature drifts etc. The high speed audio algorithms
implemented in assembler into the MCR42 maintains
the audio delay at about 1.3 milliseconds, making
it ideally for live events and to keep audio delay as
short as possible. The DSP unit also lters and de-
modulates the data carrier and communicates all the
parameters and informations to the supervisor micro
controller. The audio output goes to the digital out-
puts (AES3) or is converted in the analog domain
with a high quality 24 bits 96KHz D/A converter and
an anti-aliasing lter.

EDIT RX1: Frequency
If the specic group/channel is not locked, then can
be edited in this menu.
EDIT RX1: Squelch
This menu allows to disable the RF squelch or to
setup the desired squelch level in dBuV (note 0 dBuV
is equal to -107 dBm).
EDIT RX1: Expander
MCR42 core is a power digital audio processor that,
besides an unbeatable audio quality and exibility,
can emulate most companders systems on the mar-
ket. On this menu you can setup the audio compand-
ing chipset emulation. ENR is emulating the Philips™
SA572 and PTT digital data of Wisycom transmitters.
Other setups can be loaded on request.
EDIT RX1: Tone Squelch
MCR42 is able to detect a digital tone squelch gener-
ated by a Wisycom transmitters (MTH300/MTP30).
Tone squelch ON: when the tone squelch is en-
abled the audio is muted unless the correct carrier
is detected. Tone squelch allows to work with lower
RF squelch, increasing the coverage and the robust-
ness especially in presence of digital television car-
riers (DVB-T).
Tone squelch ADVanced: when tone squelch is in
advanced mode the receiver processes also PTT data
(push to talk): activating the command audio output
when the button is pressed on remote trasmitter.
EDIT RX1: Cong (squelch/PTT)
When tone squelch is on, output matrix between line
and com (PTT) can be congured.
When tone squelch is in advanced mode, then it
is possible to access a more complex audio matrix.
Usually Line is always thicked and Com (PTT) is
thicked on “PTT psh.” as additional return channel
(intercom).
EDIT RX1: Audio Out
It is possible to set the nominal audio from +6dBu
and -24 dBu in one dB step.
EDIT RX1: Sig. Phase
To change audio phase of 0 deg or 180 deg.
EDIT RX1: Scan
This function can be called also using the dedicated
scan button (push and keep). It allows to make a
scan over a desired frequency group.
MCR42 manages up to 2400 custom frequencies or-
ganized in 40 groups of 60 channels each. This ex-
treme exibility makes the scan function very ex-
ible.

Pag. 9
high performances microphone system
Once started a scan operation the receiver asks for
group to be used.
Then it prompts to turn off all transmitters.
Then nally start the scan!
After few seconds, scan results are displayed on a
chart.
Results can be also displayed sorted by level, mak-
ing easier to pick up the best one.
As per Wisycom standard, group 0 and group 9
are special; respectively the “center frequency”
(474,482/... MHz) and the intergap frequency (i.e.
470/478/486/... MHz). A scan on group 0 will re-
veal in few seconds the overall DVB-T occupation on
the area, while a scan on group 9 will give possible
working frequency, usable also in presence of strong
DVB-T signal (sort to speak working in the band-
guard of 2 digital television channel).
